Nathanael Greene Herreshoff I (March 18, 1848 – June 2, 1938), was an American naval architect and mechanical engineer. "Captain Nat," as he was known, revolutionized yacht design, and produced a succession of undefeated America's Cup defenders between 1893-1920. ==Biography== He was born on March 18, 1848 in Bristol, Rhode Island and was named after General Nathanael Greene. He had as brothers Lewis Herreshoff and John Brown Herreshoff. He graduated from the Massachusetts Institute of Technology in 1870 with a 3-year degree in mechanical engineering.〔(L. Francis Herreshoff, ''Capt. Nat Herreshoff: The Wizard of Bristol;'' Sheridan House, Dobbs Ferry, New York 1953 )〕 After graduation, he took a position with the Corliss Steam Engine Company in Providence, Rhode Island. At the 1876 Centennial Exposition in Philadelphia, Pennsylvania, he oversaw operation of the Corliss Stationary Engine, a 40-foot tall, 1400-horsepower dynamo that powered the exhibition's machinery.〔(Richard V. Simpson, ''Herreshoff Yachts;'' The History Press; Charleston, South Carolina 2007 )〕 In 1878 Herreshoff returned to Bristol where he and his older brother, John Brown Herreshoff formed the Herreshoff Manufacturing Company. While Captain Nat provided the engineering expertise, J.B., his brother, contributed genius-level business acumen. Despite going blind at the age of 14, J.B. suffered under no handicap when it came to making deals. For example, he did all the cost calculations of building the boats in his head—an extremely challenging but critical task under any circumstances. J.B. was responsible for negotiating with the firm's wealthy and demanding clientele, and was also a good manager, keeping up the enthusiasm of his employees. Under the partnership, the business burgeoned from about twenty employees to over 400. In 1888, tragedy struck while Herreshoff was supervising speed trials of a 138-foot, 875 horsepower steamboat named ''Say When''. After a safety valve opened to release over-pressure, Herreshoff closed it so the boat could achieve its anticipated maximum speed. But a boiler exploded, fatally injuring a member of the crew. Consequently, Herreshoff lost his steam engineer's license.〔 Two of Herreshoff's sons would also become yacht designers: Sidney Dewolf Herreshoff and Lewis Francis Herreshoff. He died on June 2, 1938 in Bristol, Rhode Island. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nathanael Greene Herreshoff」の詳細全文を読む スポンサード リンク
